Patent JP-S5843584-A (JP)
Title: Light emitting diode
Inventor: INOUE SHIYUNZOU
IPC: H01L33/30
Filed: 1981-09-09
Abstract: PURPOSE:To weeken the directivity, recognize lighting from wide ranges, clearly discriminate colors when lighting and not lighting, and realize a small size and low cost, by forming a structure wherein a casing sealing P and N layers laminates a transparent layer and a diffused layer. CONSTITUTION:When charges are injected into the P, N layers 1, 2 from lead wires 5, 6, light is emitted from the P layer 1 to the N layer 2, struck on a fluorescent layer 3, converted into a visible light and projected upward. This light advances through a transparent plastic member 7 without being attenuated by a diffusion, etc. and is dispersed by the diffusion plane of a surface 8. This diffusion plane is formed by keeping the surface of a metal mold rough when forming the casing 7 by a plastic mold. By forming the casing 7 of a transparent member with the same color as the luminous color of an LED and changing the surface diffusion layer into a colorless diffusion layer, the luminous color is produced resulting in the easy discrimination of colors due to flashes.

Title: Air lift pump
Inventor: MITANI AKIO
IPC: F04F1/18
Filed: 1977-12-02
Abstract: PURPOSE: To stabilize the operation of a multi-stage air lift pump, by fitting water level sensers to air nozzles.  
     CONSTITUTION: Water level sensing valves 16a, 16b, 16c are fitted to air passages 15a, 15b, 15c leading to air nozzles 13a, 13b, 13c for sensing the water level on each stage by means of floats 17a, 17b, 17c and opening throttle valves 18a, 18b, 18c of the air passages, respectively. Since the air passages 15a, 15b, 15c are closed at the time of starting, air flows only to the nozzle 13a on the first stage and actuates a pump 10a on the first stage to pump water up to a water tank 11b on the second stage. As the water level of the second stage tank 11b increases, the water level sensing valve 16b is actuated to open the air passage 15b, which puts a second stage pump 10b into operation to pump water up to the third stage tank 11c. As the pumping water is over, the air passage is closed. The fitting of water sensing valves to the air passages on the second and third stages can stabilize the operation of the air lift pump.
